Another term used to describe up/down counters is bidirectional.

• A state diagram is a table of states.
• All flip-flops in an asynchronous counter change states at the same time.
• Cascade means to connect the Q output of one flip-flop to the clock input of the next.
• The concept of a counter to implement a digital one-shot using HDL is not used.
• A serial in/serial out shift register transfers data from one line of a parallel bus to another line one bit at a time.
• Basic counters can be cascaded in parallel to increase the number of data bits that the counter can handle.
• The serial in/parallel out shift register transfers data from one parallel data bus to another parallel data bus one bit at a time across a single line.
• In a full-featured counter in HDL, the concept of rolling over simply means the count sequence has reached its limit and must start over at the beginning of the sequence.
• A reliable method for eliminating decoder spikes is to use strobing.
• Dependency notation is no longer used.
